Data sheet

All antennas are assembled and tested before shipping. There is no exception. All our Ham Radio antennas are pre-tuned. Once the antenna is up in the air, you should expect extremely good SWR across whole designed range, true gain and F/B as given in the table. You have nothing to tune, nothing to measure. Just put number to number and enjoy the Ham Radio hobby.

Everything is included in the 5 element 70 MHz antenna box: Antenna, balun with connector and bracket. Yours is just to assemble and have fun! As all our antennas are, this Ham Radio antenna has been designed with professional full-3D EM modelling software. The antenna is calculated with the influence of boom, balun, connectors…

4m5DX Antenna is the best performance antenna in class length of 3m.

Power options:

Antenna does not have power limit, only limitations are in used balun and antenna connector. Default maximum power input is 850 W.
